The Role

We are looking for a Senior Business Analyst — Mortgages to play a key role in delivering mortgage platform implementations for our clients.

This is a senior, client-facing role requiring deep mortgage domain expertise across origination, servicing and post-contract variations. You will own the requirements lifecycle end-to-end, from discovery through to delivery and go-live, ensuring outputs are precise, structured and fully traceable.

You will operate as a trusted advisor to clients, working across internal delivery teams and third-party providers to translate complex mortgage processes into clear, implementable solutions within a fast-paced fintech environment.

How You’ll Make an Impact

• Lead end-to-end requirements delivery for mortgage origination and servicing implementations across client engagements.
• Facilitate discovery sessions and workshops with client stakeholders to define business processes, requirements and solution scope.
• Produce clear, structured and client-ready documentation including requirements, process maps, user stories and acceptance criteria.
• Translate complex mortgage journeys, including post-contract variations, into precise and actionable requirements.
• Manage requirements traceability from initial business need through to implementation and validation.
• Work closely with developers, QA and delivery teams to ensure requirements are understood, built and tested accurately.
• Engage directly with third-party mortgage origination platforms and providers to align on integration and delivery requirements.
• Challenge and refine requirements to ensure clarity, feasibility and alignment to client and regulatory expectations.
• Build strong, credible relationships with client stakeholders, managing expectations and driving alignment across business and technology teams.
• Support delivery through to UAT and go-live, ensuring requirements are met and outcomes are achieved.

We Look For People With

• 5+ years’ experience as a Business Analyst within the UK mortgage sector, across banks, building societies or mortgage technology providers.
• Hands-on experience delivering at least one end-to-end mortgage origination system implementation from discovery through to go-live.
• Strong knowledge of mortgage servicing, including payment management, arrears, redemptions and post-contract variations.
• Understanding of UK mortgage regulation including MCOB, Consumer Duty and TCF principles.
• Proven experience operating in client-facing roles with senior stakeholders in regulated financial institutions.
• Ability to produce clear, precise and professional documentation suitable for both technical and non-technical audiences.
• Experience working with third-party mortgage platforms or sourcing systems.
• Comfort operating in a fast-paced, evolving fintech environment with shifting priorities.

You demonstrate structured thinking, strong communication skills and the confidence to lead conversations with senior stakeholders. You are calm under pressure, detail-oriented and pragmatic in your approach. You take ownership, adapt quickly and focus on delivering outcomes rather than simply producing artefacts.
